Proper Nutrition and Pet Skin Conditions
The most important determining factor in the healthy skin/coat equation is proper nutrition. No matter what else may be affecting the skin, such as allergies, infections, harsh environment, or parasites, the problem will be worse in a dog that is only barely meeting its nutrient requirements. Dogs and cats are primarily meat eaters. They will act, feel and look their best if the first ingredient on the label is meat, poultry, or fish. Diets based on grains such as corn will not properly nourish dogs and cats.
There are other reasons why a dog might be giving an unpleasant odor. It can indicate certain health conditions such as a staph infection or other bacterial infections that may require attention from your vet.
